For instance, portland cements and blended hydraulic cements for concrete in the conform to the American Society for Testing and Materials (ASTM) C150 (Standard Specifiion for Portland Cement), C595 (Standard Specifiion for Blended Hydraulic Cement) or C1157 (Performance Specifiion for Hydraulic Cements).
With a lack of standard lateritic soil for use in road construction, suitable economical and sustainable soilstabilization techniques are in demand. This study aimed to examine flue gas desulfurization (FGD) gypsum, a byproduct of coal power plants, for use in soil–cement stabilization, specifically for ability to strengthen poor highclay, lateritic soil but with a lower cement content.
